Steps for Solving Linear Equation

Multiply both sides of the equation by 2.

$$130000=800+\left(x-1\right)\times 300+800$$

Use the distributive property to multiply x-1 by 300.

$$130000=800+300x-300+800$$

Subtract 300 from 800 to get 500.

$$130000=500+300x+800$$

Add 500 and 800 to get 1300.

$$130000=1300+300x$$

Swap sides so that all variable terms are on the left hand side.

$$1300+300x=130000$$

Subtract 1300 from both sides.

$$300x=130000-1300$$

Subtract 1300 from 130000 to get 128700.

$$300x=128700$$

Divide both sides by 300.

$$x=\frac{128700}{300}$$

Divide 128700 by 300 to get 429.

$$x=429$$
